Chris has a jar with dimes and quarters in it. The jar has 7 more quarters in it than it has dimes. If the total value of the coin is $5.60, how many quarters are in the jar?
This was how i did it, but it didn't seem right.
25(x+7) = 560
25x+175=560
25x=560-175
25x=385
x=385/25
x=15.4

Question 589820: Write a point-slope equation for the line with the given slope that contains the given point.
m =-4/3 ; (7, −1)
This is what I did -4/3=y-(-1)/(x-7)
-4/3=y+1/x-7
-4(x-7)=2(y+1)
-4x+28=2y+2
-4x=2y+2+28
-4x=2y+30
-2y=4x+30
-2y/-2=(4x+30)/-2
y=4x/-2+30/-2
y=-2x+-15
